This study was aimed to explore the effects of the disinfectants commonly used in the hospitals on the tensile properties of the medical gloves with the different materials. Three types of medical gloves, composed of latex, nitrile, and polyvinyl chloride (PVC), were exposed to common chemical disinfectants to analyze the effects on the tensile properties. Ethanol-based hand rub(EBHR) and chlorine antiseptic were selected for testing. testers wear the gloves for hand hygiene. The effect on the tensile properties of medical gloves after repeated disinfection was analyzed in comparison with the control group (untreated glove was investigated in comparison with the control group (untreated glove was studied in comparison with the control group (untreated gloves). The latex gloves and nitrile gloves performed well within ten treatments of either EBHR or chlorine antiseptic. On the other hand, PVC exam gloves showed significant changes in tensile strength and elongation at breakage. This was especially true for treatment with 500 mg/L chlorine-containing disinfectant. Repeated wiping with disinfection can affect the tensile properties of disposable medical gloves,especially PVC exam gloves,which is security risk.
本研究旨在探讨医院常用消毒剂对不同材质医用手套拉伸性能的影响。选取了由乳胶、丁腈和聚氯乙烯（PVC）制成的三种医用手套，使其暴露于常见化学消毒剂中，以分析对拉伸性能的影响。选择了乙醇基洗手液（EBHR）和含氯消毒剂进行测试。测试人员佩戴手套进行手部卫生清洁。与对照组（未处理的手套）相比，分析了反复消毒后医用手套拉伸性能的变化。乳胶手套和丁腈手套在接受EBHR或含氯消毒剂处理十次以内表现良好。另一方面，PVC检查手套的拉伸强度和断裂伸长率出现了显著变化。在用500mg/L含氯消毒剂处理时尤其如此。反复擦拭消毒会影响一次性医用手套的拉伸性能，尤其是PVC检查手套，这存在安全风险。
